RAI LWAY-GATE.

SPECIFICATION forming part of Letters Patent No. 391,019, dated October16, 1888.

(No model.)

" To all whom it may concern:

Be it known that I, JOHN H. CANDEE, residing at New Haven, in the countyof New Haven and State ofConnecticut, have invented certain new anduseful Improvements in Railway- Gates; and Ido declare the followingtobeafull, clear, and exact description of the same, reference being hadto the accompanying drawings, which form a part of this specification.

[0 My invention relates to an improvement in railway-gates, the objectbeing to provide, for the protection of railway crossings, gates adaptedto be operated by the drivers of the locomotives passing over the track,combining simplicity of construction and reliability of operation, andconstructed so as to be readily pushed open by hand.

Vith these ends in view my invention consists in railway-gates havingcertain details of construction and combinations of parts,as will behereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of a pair of gatesembodying my invention, and Fig. 2 is a view thereof in side elevation.

As herein shown, there are two gates, and being alike in construction,only one will be described. Each gate is provided with a horizontalgate-beam, A, swinging through an angle of about forty-five degrees, towhich it is limited by the posts 13 and C. The inner end of the beam isattached by a pivot, D, to the lower end of an upright movable gateheadE, having its upper end adapted to play in a staple, F,applied to theworkingface G of the gate-post H,which, as shown,isrhombicin transversesection. The lower end of the gate-head E is provided with a bifurcatedo arm, I, carrying a roller, J, traveling on a ridge, K, runninglengthwise of the upper face of a rocking carriage, L, forming a supportfor the gate-head, and pivoted midway of its length upon a block, M,offsetting from the said working-face of the post. A frame, N, securedto the ends of the carriage, passes through the arm I at a point abovethe roller carried thereby, whereby the gate-head and roller are held intheir proper relations to the carriage. A stay-rod, 0, attached to theouter end of the swinging gate-beam A,is connected at its upper end to abar, 1?, projecting from the working-face of the post at a right angletherewith,and arranged to slide in and out of a head, Q, attached to thetop of the post,and having a set-screw, R, for holding the bar in anydesired adjustment. The gate-beam isin its central position when midwaybetween the two posts, 13 and C; or in other words, when it makes aright angle with the working-face of the gate-post. This being the case,and the bar 1? being located in line with the beam when the same is inits central position, it will be seen that as the beam swings away fromsuch position the stay rod will pull 6 against the outer end of thebeam, and so check or break its movement and prevent it from slamming,so to speak, against the posts B and C. By adjusting the bar P thechecking action of the rod may be regulated as desired. A bell-cranklever, S, carrying the hammer ofa gong, T, is pivoted to the postH, soas to be operated in sounding the gong every time the gate-head islifted, which is every time the gate-beam is swung open and closed. Forthe purpose of shifting the movable gate-head, the carriage is rocked onits center. This is done through the drivers of the locomotives as theypass over the track U.

One end of the frame M is attached by a short link, V, to the upper armof a bell crank lever, \V, pivoted to the outer edge of the gatepost andhaving its lower arm connected by a rod, X, with a horizontal four-armedpivotal head, Y, located between the two gate-posts and connected withthe lower arm of the corresponding lever of the opposite gate-post. Thishead is also connected by a long wire, Z,

to a gate-closing dog, A, located up the track in position to be engagedand operated by the drivers of the engines, and by a wire, B, to acorresponding gateclosing dog, C, located down the track. These dogsoperate to shift the carriages of the two gates so as to swing thegate-beams closed,and are effectively actuated in only one direction,and that in approaching the gates. The opposite end of the frame M ofthe carriage is connected by a link, D,

to the upper arm of a bellcrank lever, E, pivoted to the inner edge ofthe gate-post and IOO having its lower arm connected by a wire, F,

to a dog, G, located between the posts, connected, also, to thecorresponding lever of the opposite post, and arranged to be effectivelyoperated in either direction by the drivers of the locomotives,so as torock the carriages for shifting the gate-heads so as to effect theopening of the gates.

The gate-head works upon the flat outer face of the gate-post, which isset so that the gate-beam will be at a rightangle with such face when itis in the center of the arc in which it swings. This arrangement securesthe freest action of the beam, which opens and closes under the actionof gravity by changing the center of gravity in it by shifting theposition of its inner end.

When the gates are closed, as shown by the drawings, the carriages areinclined outward and the lower ends of the gateheads moved outward. Thenwhen the train passes them it trips the gate-opening dog,which isadapted to be effectively operated from either direction. The trippingof this dog operates to shift the carriages so as to incline theminward, and so throw the lower ends of the gate-heads inward. Thisshifts the center of gravity in the gate-beams and causes them to openand swing outward until they are stopped by the flying posts B. Thegate-beams being now open, they .will be closed by the tripping ofeither of the gate-closing dogs, whereby the carriages are inclinedoutward again,with the effect of shifting the lower ends of thegateheads outward, and so again changing the center of gravity in thegate-beams, which at once leave the flying posts and swing back to theposts adjacent to the track.

Under my invention very little power is required for opening and closingthe gate-beams; nor does the fact that the operating-dogs are sometimesstruck quickly and at other times slowly, according as the speed of theengine may be fast or slow, interfere with the successful operation ofmyinvention; It is also to be noted that the beams may be readily pushedopen from the inside for escape in case of being caughtin between them.The apparatus is, moreover, simple and cheap of construction, easily putup and kept in repair, durable in use, and reliable and effective inaction.

It is apparent that in carrying out my invention I may make some changesand alterations from the construction herein shown and described. Iwould therefore have it under stood that I do not limit myself to suchcon struction, but hold myself at liberty to make such changes andalterations as fairly fall within the spirit and scope of my invention.
